What I have tried:

I already used with start and end Date to generate days

SQL

declare @EndDate as datetime

set @StartDate='03/01/2019'
set @EndDate='03/06/2019'

;WITH    AllDays      
AS ( SELECT   @StartDate AS EntryDate, (CASE WHEN DATENAME(dw, @StartDate) = 'Sunday' THEN 1 ELSE 0 END) AS [issunday]      
   UNION ALL      
   SELECT   DATEADD(DAY, 1, EntryDate),(CASE WHEN DATENAME(dw,  DATEADD(DAY, 1, EntryDate)) = 'Sunday' THEN 1 ELSE 0 END)      
   FROM     AllDays      
   WHERE    EntryDate < @EndDate )      
SELECT EntryDate, [issunday] into #tempX   
FROM   AllDays OPTION (MAXRECURSION 0)  

Select * from #TempX

Try "something" because no one has a clue how you plan to get the "input" in or the "output" out.

Instead of regenerating it each time, I'd pregenerate it: two tables containing two columns: Month and Day, with a row for each day of the year (the second table is for leap years)
Then it's just a case of splitting the date into @MONTH and @YEAR, then using a simple SELECT on the correct table:

SQL

SELECT Day + '-' + Month + '-' + @YEAR FROM MonthNonLeapYear WHERE Month=@Month

Much more efficient than loops or CTEs and temporary tables.
